UNITED STATES PATENT OFFICE.

NOBLE ANDREW FISHER, OF SACRAMENTO, CALIFORNIA.

CLUTCH FOR CABLE RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 310,397, dated January6, 1885.

\ Application filed August 9. 1884. (No model.)

To all whom it may concern.-

Be it known that LNOBLE A. FISHER, a citizen of the United States,residing at Sacramento, in the county of Sacramento and State ofCalifornia, have invented certain new and useful Improvements inClutches for Cable Railways, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention has relation to improvements in clutches for cablerailways; and it consists in the construction and novel arrangement ofdevices, as will be hereinafter more fully set forth, and particularlypointed out in the claims appended.

The object of my invention is to provide a cheap and simple clutchingdevice for cable railways, by which the rope may be prevented frompassing too far into the jaws and catch ing or binding therein. Thisobject I accomplish by the means shown and illustrated in theaccompanying drawings, in which Figure 1 is a representation of aperspective of my improved clutch, and Fig. 2 is a similar view showingthe same constructed in a modified form.

Referring by letter to the said drawings, A indicates thesuspension-plate, which is provided longitudinally with the centralvertical slot, a, in which is arranged the grip-operating rod B. Thisrod is provided with slideblocks 1), which are designed to guide thesaid rod in its up and down movements through the suspension-plate, andthe said rod is also connected at its lower end to a transverse link orbar, 0, which is also provided with guideplates d, and is pivotallyconnected at its opposite ends with arms D, which are also hinged attheir opposite ends to the lateral arms I of the hinged clutch-jaws.

I sometimes find it preferable to construct the device as shown in Fig.1, in which case I hinge two jaws, E, to the lower projecting branches,F, of the suspension-plate by means of a transverse bolt, G, thesuspension-plate having four of the branches, and the arms I of theclutches turned outwardly in opposite directions. The outer or endbranches, F, of the suspension-plate are forked, as shown at e, and

the arms thereof are perforated transversely for the reception of thejournals of horizontal transverse friction-rollers H, which are designedto prevent the cable from passing beyond the proper point in the clutchor clamping-jaws.

In the construction shown in Fig. 2 but one hinged jaw is employed, theother being fixed, or a continuation of the suspension-plate, and thehinged jaw is forked or provided with suitable bearings above thecable-groove in the respective jaws of the clutch, for the reception ofthe transverse horizontal friction-rollersH. Thehingedclampingjawsarerespectively provided on their inner longitudinal sides with concave orother suitable grooves, h, for the passage of the cable, and thesegrooves are provided at suitable intervals with frietion-rollersg,having vertical bearings and arranged relatively at right angles to thesaid rollers H. Thus it will be seen that it does not deviate from thespirit of my invention to construct a clutching device under both formsillustrated, and while I prefer to use such clutches in connection withthe patented devices issued to me December 11, 1883, it will be readilyperceived that they may be used on roads of various constructions, andthe jaws operated by any suitable mechanism.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is v 1. In a cable-clutch, as described, thecombination, with the jaws, as E E, having semigrooves h, offriction-rollers, as g, journaled in the jaws and projecting into thegroove, as and for the purposes set forth.

2. The cable'clutch described, having the friction-rollers g, journaledin the jaws and op erating in the groove, and having also the transverserollers H, journaled in fixed bearings and directly above the groove,all combined and adapted to serve as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

NOBLE ANDRE? FISHER.
